Role	Required	Description
Systems Programmer (C/C++)		Gets familiar with performance profiling: uses time, perf stat for basic metrics. Measures execution time of system functions, analyzes simple bottlenecks.

Role	Required	Description
Systems Programmer (C/C++)		Conducts system profiling: perf record/report, hardware counters (IPC, cache miss), off-CPU analysis. Builds flame graphs for kernel code, analyzes scheduler latency.

Role	Required	Description
Systems Programmer (C/C++)		Performs deep performance analysis: PMU-based sampling, last branch record (LBR), Intel PT. Conducts end-to-end latency analysis from hardware interrupt to userspace delivery.

Role	Required	Description
Systems Programmer (C/C++)		Defines performance analysis methodology for the team. Establishes benchmark suite for kernel subsystems, automates performance regression detection in CI.

Role	Required	Description
Systems Programmer (C/C++)		Shapes enterprise performance engineering practice. Defines performance SLA for system components, builds observability infrastructure for production kernel systems.
